A request for help about train process,log file,code arguments.

[Video54367]

Thanks for your work. I thoroughly enjoyed reading the paper and I feel confused about the train process,I notice that you set two training orders,and the second order seems to fine tune the first-training result.Is that the necessary procedure for the whole training? Could you give me some specifics about this issue？
In addition, after training, I only found the weight file with '.th' as suffix under the folder ckpt/TATT or ckpt/TATT_ft, it seems that there is no log file.Where I can find it?
About the parser.add_argument() function in your code file. I noticed that the help parameter is left blank for several arguments in the parser.Could you please provide a brief description for these arguments? This would be greatly helpful for users who are new to your program, as it would give them a better understanding of the purpose of each argument and how to use them correctly.
I understand that you may be busy, but if you could spare a moment to update the help messages, it would be much appreciated.
I'm just a beginner,forgive my ignorance.Again,thank you so much!
